  Log Message:
  -----------
  [Driver] Add disabled-by-default -Wuse-ld-path for the deprecation warning for -fuse-ld=/abs/path

The warning is currently not under a -W option, so it cannot be suppressed.
This is annoying for the widespread build system Bazel when specifying the path to gold

I have notified them about using --ld-path= forwards
https://github.com/bazelbuild/bazel/pull/8580#issuecomment-694321543
but we have to give some transitional period.
